This invention relates to filling replenishing looms and is moreparticularly directed to means for preventing sloughing' or displacementof the yarn upon fillingcarriers while in the hopper. I

In the prior patent to John T. Kirk No. 1,595,045, dated August 3, 1926,and in the subsequent patent to Harry A. Davis, No. 1,662,000, March 6,1928: there was shown and 3 described an anti-sloughing device adaptedto act upon the mass of filling on the carriers in the hopper andprevent endwise displacement thereof. The present invention is a furtherdevelopment of the anti-sloughing device with a view of providing eachof the filling carriers in the hopper with an individual anti-sloughingdevice independent of the other filling carriers in the hopper.

Filling carriers are usually provided with filling or weft threads laidin conical layers upon the carriers and when the filling car riers arein the hopper the ends of the filling or weft threads are secured tosome fixed part, so that the vibrations of the loom and the rotation ofthe hopper itself is liable to cause the conical end windings of fillingto move longitudinally of the filling carriers and become displaced withthe result that on replenishment of filling the yarn is liable to bebroken during transfer, or the filling may pass in coils over the end ofthe carriers during the shuttle movements. 4

In accordance with the present invention the hopper for the fillingcarriers has a series I of supports or fingers preferably of resilientcharacter to present a filling engaging portion or member incontactwithtlie conical end windings while the filling carriers are inthe hopper. In other words, each of the fillling carriers is providedwith'an individual anti-sloughing device separate and independentfrom'all the other anti-sloughing devices carried by the hopper. Insome'cases it is desirable to provide the transferrer with a tipengaging portion in addition to the head engaging portion of thetransferrer and in order that thetip' engaging portion may beeffectively 'during transfer it is preferable that it engage the end ofIO the filling carrier or bobbin itself.

With these ends in View the anti sloughing devices of the presentinvention are mounted upon the end portion of the hopper'and extendtherefrom adjacent the conical windingson the filling carriers at oneside of the plane passing through the axis of the rotary hopper and thelongitudinal axisof the filling carriers. The" result of this is thatthe individual anti-sloughing devices will be H lateral atone side ofthe conical end wind 6 ings when a filling carrier is in transferringposition, so that the transferrer may be provided with a tipengaging-portion to contact with. the end of the filling carrier duringtransfer.

The above and other features of the inven tion will best be made clearfrom the following description and accompanying drawings of one goodform thereof. V

In the drawings Fig'. 1 is aperspective' View of a provided with thepresent invention;

Fig. 2 is 'a-perspective view of one of the supports or fingers of theanti-sloughing deh vice detached; 1.

Fig; 3 is a perspective View of one type of hopper pad which may bereversibly applied to the fingers to thereby providefor wear;

Fig. 4 is an enlarged sectional elevation showing the relative positionof a filling carrier and anti-sloughing device constructed in accordancewith the present invention;

'Fig. ,5 is a plan view looking upon a filling carrier in the hopperwhen in transferring position and Fig. 6 shows a modified form of pad ofyielding material.

The loom frame 1 may be of usual construction and mounted upon the loomframe is the stand of the rotary hopper comprising a foot portion 2 andan end or cover plate 3and mounted in the cover plate is the stud oraxial support 4 on which the rotary hopper is mounted for turningmovement.

Extending from the hopper stand is a stud or, dead shaft 5 on which ismounted the transferrer 6 which is-normally under the influence. ofspring 7' for maintaining the transferrer :in its upper or inactiveposition. Extending downwardly from the hub of the usual constructionand as shown'in the pres---- ent instance of the mvention the outerhead" portion 11 of the hopper is provided with tip engaging members 12normally under the influence of springs 13 -to'cause -the tipen-. gagingportions to press longitudinally upon the: ends ofthe fillingcarriersinrthe hopper.

The 'outerhead'portion 11 of the hopperis provided with a circularmember 14 which forms a convenient .support'ifor. the "anti sloughing.devices or fingers as will presently.

appear. 7 V

The anti-sloughing devices or '.fingers'15 may lee-variously contrived'and be supported from the hopper'in a convenient manner; but as heremshownzas itigOOdPIlCtlCltl:fOIDTOf the-invention, each finger 15lhasJ-aspring clip portion 16 bent incontouri to engage the. flange or ringl lon the hopper whereby'the fingers may be individually'and'readily de'-'tached and applied. The spring cl-ip'16is conveniently formed asindicated in Fig. 2 whereinthefupper portion 17 engages the top of theflange or ring 14 while the lower portion 18 passes about-the loweredgeof the flange or ring 14 and serves 'by'itsispring actionto-maintain its associated'finger in 0perative position .on1the hopper..i

Each finger is formed preferably as.indicated; in Fig.2- 2 wherein aresilient portion extends from the spring clip atsthevlateral side ofits associatedfillingrarrierin the hopper. Each resilient finger is.preferably, though not-necessarily, provided with a pad ofyieldingmaterial such for instance as that shown in Fig. ii wherein the pad 19is indicated as formed of a block-of felt or :other like suitablemateriahprovide'd withan open ing20 in-which the resilient arm 15 maybeinserted after straighteningiout the laterally bent portion 21 thereofand after the resilient arm-15 has been passed through irthezpad asdescribed, the end portion 21'Jis bent "laterally to maintain thepadiinfoperative po sition on the finger.

The pad of yielding materi alt mayz'be variously contrived 1 and v amodification the reef is indicated in F ig;s6 whereinfthe pad 22 isformed of avmaterial' of suitable character; the edge portions whereofare secured to-; gether byclips 23 to-thereby'form an opening 24: in thepadfor the reception-.of'theresilient;

arm 15 of the-anti-sloughing device.

. As hereinbefore 1nd1ca-ted the anti-slough mg devices extend inwardlyfrom the outer end member of the hopper at thexla teral side portion ofthe associated filling carrier, such that when a filling carrier hasreached transfer position in the hopper the anti-sloughing device willpresent no obstruction to the downward movement of a' tip engagingportion mounted=on the transferrer, so that said tip engaging portion'asrindieated inFig. 1 at 25 may during this downward movement engagethe exposed end portion 26 of the filling carrier or bobbin andineonjunction with the usual 'he'adportion of the transferrer cffeet aproper transfer of the filling carrier to the shuttle;

Theabove described condition is illustrated in Fig. 5 wherein the linea?; represents a plane-passing throughthe axis of the.hop per andthe'longitudinal@ axis of the carrier, and it will be noted from Fig. 5that whenwthe filling carrier-is in transferring position theanti-sloughing-:-device bears upon the conical end windingsat one sideof such plane. so that it presents no obstruction to the transfer of thefilling carrier fromthe hopper: to the-shuttle by the engagement of theheadand tip 'engagingportions of the transferrera 7 Fromi the-.=construction described .it will be apparent: that- 'the present.invention pro-V videsan individual anti-sloughing device for each of-thefillingcarriers in the hopper and that such anti-sloughing devices-areindividually orself-contained irrespective of the.

other anti-sloughing devices on the hopper. It1will beapparentfromthedisclosures herein that the individual and separateantisloughingedevices afford simpleand effective means for preventingsloughing or: displace:

I Should the anti-sloughing devices comprisemot only the-resilientfingers 15 but a reversible pad=as-well,'it is obviousthat upon undue:Wearing of'one portion of the pad as herein described the pad itself maybe-.re-- versed in position on the resilientfinger to thereby present anew "and fresh anti-sloughing surface to bear :against the conical: end
